Let's take a look at the table below: Think about how we can add data to this table more easily in database SQL Server. Careful observation of this table we are not difficult to find that the ID field of this column of data recharge is a rule to follow, it is an increase in the number of columns, to the data table to add such data is there a simple way? This refers to the problem with the SQL Server identity column. I have some informati

PRIMARY KEY ConstraintA table often has a combination of columns or columns whose values uniquely identify each row in the table. One or more of these columns is called the primary key of a table, through which you can enforce the entity integrity of a table. You can create a primary key by defining a PRIMARY key constraint when you create or change a table.A table can have only one PRIMARY key constraint, and a column in a PRIMARY KEY constraint cannot accept null values. Because the PRIMARY KE

Oracle for most security software pilot programs, it is difficult to explicitly calculate the return on investment. It's like going back to calculating the benefits of some of the things that have not happened. However, the Identity Management pilot program differs. The cost savings resulting from reduced management time and increased employee productivity are clearly visible and measurable because of reduced time spent on password-reset. These cost s

In the previous article, we have used WIF to build a simple authentication program based on mvc4. In this article, we will discuss what WIF is, and how it works. Then, starting from the next article, we will implement the Single Sign-On function. Challenges of identity As mentioned in the previous article, most developers are not security experts. Many people feel very uncomfortable with identity verifica

After an INSERT, select into, or large-capacity copy statement is completed, @ IDENTITY contains the last Identifier value generated by the statement.
